I have installed engineered hardwood all throughout my house, in addition wood base trim (which comes pre-primed). Now that my projects are done, I dont want to throw away the wood, incase I can use it for repairs or for a small future project, but its taking up space in my basement. Can I store the hardwood in my (non-climate controlled) shed, or will the varying weather/humidity render my wood useless for future projects?

I live in Maryland (winter hovers around 20 degrees f, and summers averaging around 90 degrees f) if that helps. The engineered wood is still boxed, the trim is not.

Can't say for sure how well it will hold up, but it will expand and contract in size due to temperatue and humidity differences. Before using it however I would move it to a climate controlled setting a week ahead of time before you plan on using or installing it in the future. This will give it time to acclimate and adjust.

Engineered floors typically have a 'max humidity' level that they tolerate, but I think that's based on it being installed. So, it may have no effect on flooring that hasn't been installed yet (aside from maple's valid point that regardless of where you store it, you need to acclimate it to the installation space prior to final installation).

Thank you, I understand the re-acclimating aspect of the flooring, I just wonder if the humidity could warp/distort the wood to such a point where it would render the hardwood/trim "uninstallable"

Asking the manufacturer would probably yield the best answer as they know their product and how it will respond
